BUN K.

To all whom it may concern:

Be it known that I, RoLLiN WooLLEY, a citizen ofi the United States, residin at Carlton, in the countyof Yamhill and `tate of Oregon, have invented certain new and useful Improvements in Bunksg and I do hereby declare the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

\ This invention `relates to a novel construction of bunk, that is to say, a device for use on wagons or trucks for hauling poles and piling.

The fundamental object of the invention is to provide a bunk having movable blocks so that the latter may be moved to accommodate the size of load desired, the blocks dispensing with the use of chains for this purpose and eliminating all dangerof the load shifting. y

A further object is to provide a novel con` struction of means for removably locking the blocks in adjusted position against upward dis lacement. y i y further object is to provide. a novel construction of tool in the nature of a lever for iently moving them lengthwise of the chan-l nel bars which support said blocks.

Further objects relating to certain improvements, more especially in structural detail, will appear as the specification proceeds and thenature ofthe invention is more fully disclosed.

The invention in its preferred form is clearly disclosed in the accompanying drawin s, in which:

igure 1 is a view in side elevation of the bunk constituting my invention;

Fig.`2 is a central vertical longitudinal sectional view thereof;

*Fig Sis `a fragmentary view in' partial section of the bunk;

Fig. 4 is a fragmentary central vertical longitudinal sectional view of the bunk, showing the position of one of the blocks in the unloading position of the bunk;

t Fig. 6 is a detached detail view in perspectiveof said locking dog, and F ig. 7 is a similar view of the dog which is used to manipulate the block. Y

Referring now in detail to the drawings:

1 designates a channel bar adapted to be channel bar and curved at its ends, as shown i i at 6, beyond the ends of said channel bar, the terminal of each of said curved end portions lying beneath the corresponding end of the channel bar, as shown at 7. Each of said ribs 5 is disposed a suitable distance above the bottom of the corresponding side flange 3, said ribs 5, 5 constituting tracks to guide the blocks (more particularly hereinafter described) in their movement lengthwise ofthe channel bars, to position said blocks in adjusted position.

In connection with each channel bar 1 a )air ofcomplemental, similarly constructed locks are used. Each of said blocks is peculiarly formed, preferably of metal, and comprises an end portion 8, provided at its sides with downward extending parallel arms 9, 9, the upper edges of .said arms be ing beveled, as shown at 10, and said arms terminating at their free ends in outwardly projecting pintles 11, 11, adapted to be seated leneath the ribs 5, 5, as clearly shown in ins 12, 12 connect the bars 9, 9 between the ends thereof, and serve to brace said arms. One of said pins 12 is disposed adjacent the end 8 of the block so that astake 13 may be projected between said pin and said end 8` and be held thereby against sidewise displacement. Said stake 13 is preferably of a width to fit closely between the arms 9, 9.

Carried by the end 8 of each block on the face thereof, opposite the face `which carries the arms 9, 9, 1s a transversely extending plate 14 adapted to seat in the notches 4.

Carried by the plate 14 is one or more safet dogs 15, one thereof being shown in rawin as carried by each plate, said safety dog ing pivoted, as shown at 16, t0 said plate, and being provided with a toe 16l adapted to be projected beneath the adjacent rib 5, thus holding the block against upward displacement when said block has been moved to an adjustedposition. F ig. 5 shows the block in full lines in operative position,`

dog is providedwith a handle 16 for con- Vot` the" channel bar 1,the tool or lever 18 is depressed, thus forcing the plate 14, with the attached block, upward, thus disengaging said plate from the grooves fl, whereupon by pulling-up the lever 18, the block may be shifted, longitudinallylof the channel. bar 1 to adjusted position,` so that said plate 14 may engage a different pair of notches 4.

Fig. 4l `discloses .thegposition of the block Vin the4 unloading ,positiono'f the device, and in this position it lwill be noted that Vthe block ,has been moved to the end of the bottom of the channel bar 1, and is. swung downward out ofthe way. of the logs on said channel bar, so that the logs may be unloaded.

What I: claim to be new is:

1. A bunk comprising a channel'bar, longitudinally extending ribs carried von the inner faces, of the upright Yfaces of said channel bar abovethe bottom thereof, blocks slidable` longitudinally of said channel bar and yprovided 'with terminals disposed beneath said ribs, the latter thus constituting tracks to guide said blocks in their movement'longitudinally of the channel bar,r and meansv carriedbyg said blocks for holding the same, in `adjusted position, said holding means comprising a.. plate carried by each Iblock yand adapted to engage the upright V.flanges oi' ,the channel bai', the upright flanges of said channel barebeing for this purpose-provided with notches Aadapted to reeeivefsaid plate.. i

, 2. A bunk comprising a channel bar, longitudinally. .eXtending ribs Acarried on the innerifaces of the` upright faces of ,sa-id channel bar above the bottom thereof, blocks slidable longitudinally of said channel bar and provided with terminals disposed beneath said ribs, the latter thus constituting tracks to guide said blocks in their movenient longitudinally of the channel bar, and

means carried by said blocks for holding the same in adjusted position, said holding means comprising a plate carried by each block and adapted to engagethc upright flanges of the channel bar, the upright flanges of said channel bar being lor this purpose provided with notches adapted to receive said plate, and a locking dog carried by each plate and adapted to be projected beneath one of said ribs to hold the block against upward displacement.

3. A bunk comprising a channel bar having ribs formed along the inner faces ot said channel and curved downwardly at the outer ends, a block having arms adapted to engage under the ribs and slide longitudinally of the channel and pivot about the end ot the channel in engagement with the down-turned ends ot the ribs, and means carried by the blocl; lor engagement with the channel at adjusted positions.

4. A bunk comprising upstanding side bars having inwardly projecting ribs forniing guides, said guides provided with stops at their extremities, a. block slidable longitudinally in the channel and havng means for engagement therewith at adjusted positions, and means carried by the block engaging under the ribs and forming hinges for the swinging of the block about the Yend of i and beneath the bars in engagement with the stops.

5. A bunk comprising upstanding substantially parallel bars having alined notches formed in their upper edges', a block disposed between the bars and having means for engagement selectively in the several notches, guides formed in the interior ofi the bars and terminating at the end of said bars in stops, and means carried by said block engaging said guides, forming pivots for the block to swing about and beneath the end ot the bars in engagement with the stops.

6. In a bunk, longitudinally extending guides terminating in hooks, blocks slidablc in the guides and having means for engagement at selective longitudinal positions and to engage said hooks and swing pivotally about the ends of said guides.

In testimony whereof I hereunto aiiix my signature,l
